Hi!)
As a professional C#/.NET developer with focus at Data scrapping and web crawling, I'm really interested in your project!
I've read your task and checked links and files attached, and yeah, I'm able to do it really fast and elegant ;)
Additionally, I can provide you all the source code of this project, thus you can modify it later, if you want.
It will take about 1-2 days (depending on day, we start), and cost 20$ (written in Bid Amount).
Best wishes ;)
